SPECIFICATION forming part of Letters Patent lilo. 622,325, dated April 1899, Application filed February 10,1898. fierial No 669,764. (No model.)

To all whom it may concern.-

Be it known that I, W innmn H. BURNETT, a citizen of the United States, and a resident of Poughkeepsie, county of Dutchess, and State of New York, have invented certain new and useful Improvements in Pipe Connections, of which the following is a specification, reference being had to the accompanysimilar letters of reference indicate corresponding parts.

This invention relates to an improved connection more especially adapted for elbows or pipes connecting water-closets with the soilpipe and with which flushing and venting pipes are ordinarily used. j

The principal object of the invention is so to arrange the flushing and venting pipes relatively with the main pipe or elbow that neither pipe connection will interfere with the ordinary flow through the main and soil pipes and so that this flow through the main pipe will not interfere with the inward flow from. the flushing-pipe or with the outward flow inflow will not flow.

Another object of the invention to provide a pipe connection of this character which occupies little vertical space between the floor on which the closet stands and the subjacent ceiling of the next story of a building and will admit of easy and fluid-tight coupling of the flushing and venting pipes with the main pipe or elbow in this shallow space.

The invention will be. hereinafter fully described, and specifically set forth in the annexed claims.

Inthe accompanying drawings, Figure 1 is a side elevation of the device and a section of the flooring and ceiling; and Fig. 2 is a plan view of the same, a portion of the flooring being broken away.

In one adaptation of my invention 1 employ an elbow A, preferably of cast metal. Said elbow upon its upright section dis preferably provided with a series of annular ribs l5, formed integrally therewith and adapted to retain in position gaskets of the form and material suitable for making a water-tight interfere with the venting outferred in this instance to screw the said soilpipe G into the elbow A, said elbow being provided with a suitable thread upon itsin terior for this purpose. I prefer to form integrally with said elbow A the Y-spurs or thilnbles D D, having passages therethrough communicating with theinterior of the elbow A. As herein shown, a suitable thread is out upon the inside of Y-spurs, into w ich the gas-vent pipe E and the pipe-fixture F- are adapted to screw. A water-tightjoitis thus made without the necessity of cutting holes through the walls of the elbow and securing the pipes thereto by means of lead or, other soft metal. formed on the outside of the spurs or thimblcs to match interior threads on the pipes E F in coupling the elbow and pipes A E F by screw-joints in a simple and efiiectivemanne in the small space between the floor and the ceiling.

The spurs D are project-ed from the side walls of the elbow A at a suit-able angle, Fig. 2, to prevent the water flowing through the pipe F from entering the inner mouth of the gas-vent pipe E. Said spurs D are preferably located upon the upper half-section of the horizontal portion of said elbow, as shown in Fig. 1, the object thereof being to prevent the interference of any water which may be standing in or flowing through the soil-pipc with the action of the water-supply pipe F and the gas-vent pipe E.

In operation any water which may ilow down through the upright portion of the olbow A passes out through the soil-pipe in the usual manner. Any sewerage-gas which may have accumulated in the soil-pipe is free to escape through the gas-vent pipe E, said pipe being above the central line of the horizontal portion of said elbow. At the same time any water which may be flowing through the fixture F will be projected at an angle across The screw-threads maybe" t action of pipes E F, it is immaterial how the the soil-pipe without creating an eddy opposite the month of the gas-vent E, and thereby checking the same.

The angle shown in Fig. fl is notessential to the operation of the device. T-his'angle may be changed to one more acute or to one more obtuse so long as the line of discharge from the pipe F clears the mouth of the gasvent E by a sullieient distance to prevent an eddying action in the mouth thereof.

v In so far as concerns the relative arrange ment of the branch pipes E F with their'cem ters or axial planes above the axial plane oi. the elbow or main pipe A to prevent flow through it interfering with the most effective branches are coupled with-the main pipe or elbow; but the screw-threaded connection is specially advantageous,-as' it may be most easily made in the shallowspace between the floor and ceiling after the elbow is connected to the soil-pipe. I

Having-thus described my invention, what I claim as new, and'tlesire tnsecu re by Letters Patent, isv 1. A pipe connection comprising a main pipe or elbow and two branches therefroin' adapted respectively for flushing and venting and located with their axes or centers above the axis or center of tlio tially as described.

2. A pipe connection comprising a main pipe or elbowland two branches therefrom adapted respectively for flushingand venting, said branch pipes having a. screw-thread connection with the main pipe and located. with.

main pipe, substanand two angularly-disposed branches coup ling with the soil-pipe end of the elbow and located with their central planes above its central-plane or axis, substantially as described.

5. A pipe connection comprising an elbow adapted for connection at one end with a water-closetand atthe other end with a soil-pipe, said elbow having two integral an gularly-disposed and screw-threaded thimblesadapted to receive flushing and venting pipes and located with their central planes above the central plane or axis of the elbow, substantially as described.

In testimony that I claim the foregoing as m y invention I have signed my name, in presence of two witnesses, this 4th day of Februar 1898." 4 I NILLIAM II. BURNETT.
